Randomized Controlled Trial Comparative Study
The measurement of lung volumes using body plethysmography: a comparison of methodologies.
The statement of the American Thoracic Society and European Respiratory Society on the measurement of static lung volumes (SLV) suggests a preferred and alternate method for measuring and calculating SLV. ⋯ Differences in FRC, VC, RV, and TLC obtained using the preferred and alternate measurement methodologies exist in the clinical setting in select classification groups and individuals. Differing calculation methods dependent on measurement method used may be unnecessary.

Effects of exercise training on pulmonary mechanics and functional status in patients with prolonged mechanical ventilation.
The functional status and outcomes in patients with prolonged mechanical ventilation (PMV) are often limited by poor endurance and pulmonary mechanics, which result from the primary diseases or prolonged time bedridden. We evaluate the impact of exercise training on pulmonary mechanics, physical functional status, and hospitalization outcomes in PMV patients. ⋯ Subjects with PMV in our RCC demonstrated significant improvement in pulmonary mechanics and functional status after exercise training. The application of exercise training may be helpful for PMV patients to improve hospitalization outcomes.

Randomized Controlled Trial
Effect of slow expiration with glottis opened in lateral posture (ELTGOL) on mucus clearance in stable patients with chronic bronchitis.
Slow expiration with glottis opened in lateral posture (ELTGOL, l'expiration lente totale glotte ouverte en infralatéral) has been used in clinical practice to improve mucus clearance from peripheral airways. The purpose of this crossover study was to evaluate the effect of ELTGOL on mucus clearance of right and left lungs, especially of peripheral lung areas, in stable patients with chronic bronchitis. ⋯ ELTGOL was efficient in increasing peripheral airway clearance in dependent lung of patients with chronic bronchitis, most of them with mild to moderate COPD.

Randomized Controlled Trial Comparative Study
Influence of 4 interfaces in the assessment of maximal respiratory pressures.
The measurement of maximal respiratory pressure (MRP) is a procedure widely used in clinical practice to evaluate respiratory muscle strength through the maximal inspiratory pressure (P(Imax)) and maximal expiratory pressure (P(Emax)). Its clinical applications include diagnostic procedures and evaluating responses to interventions. However, there is great variability in the equipment and measurement procedures. Understanding the impacts of the characteristics of different interfaces can augment the repeatability of this method and help to establish widely applicable predictive equations. The aim of this study was to evaluate the influence of 4 different interfaces on a subject's capacity to generate MRP and the impact of these interfaces on the repeatability of these measurements. ⋯ P(Imax) and P(Emax) values seem not to be influenced by the different interfaces studied, suggesting that patient comfort and availability of interfaces can be considered.

Randomized Controlled Trial Comparative Study
A randomized trial of conventional chest physical therapy versus high frequency chest wall compressions in intubated and non-intubated adults.
Conventional chest physical therapy (CCPT), applied by therapists using cupped hands to perform percussion, is commonly used in hospitalized adults. However, increased work load demands and occupational health concerns (eg, carpal tunnel syndrome) limit the overall utilization of this therapy. Therefore, we conducted a study to compare the overall effectiveness of CCPT to high-frequency chest wall compressions (HFCWC) applied via a vibratory vest. ⋯ This study was inadequately powered for the primary outcome of interest and hence we cannot make recommendations on the preferential use of HFCWC or CCPT for intubated and non-intubated adult patients. HFCWC was associated with statistically better comfort scores. (ClinicalTrials.gov registration NCT00717873.).
